LAV audio mixer: Prologic II, The surround channels phase? #570

Are the surround sound channels shifted with 90 degrees phase before mixing? According to the Dolby doc that results in the best sound effect compared to real 5 channels. Thanks for checking that.

Also I wonder how to activate the Dolby Pro Logic matrix correctly. Does the Pro Logic matrix overwrite the three mixing values of Center/Surround/LFE so correct sound is heard whatever those values are?
